pretty good once it's set up

Crutchfield customer from Boxford, MA on 9/3/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

I ended up having to get 3 units to get one that was working. However, Crutchfield was great and kept sending out new units. Once I got the third unit and plugged in the wiring which had been completed with the first one, i was a little underwhelmed with the volume. It turns out that if I turn my head unit Kenwood KMR sub woofer setting all the way up to 15, and I turn the gain all the way up on the Bazooka, and I turn the remote all the way up, it's alright. I installed this on a 23' boat. I have an Alpine amp powering 4 - 6 1/2" Infinity marine speakers. The Bazooka is in the cuddy. It does add a nice texture to the sound, and it does fill out the low end nicely. I just assumed that turned all the way up, it would overpower the rest of my system and I could run this down at a more comfortable setting. I am using the RCA connections. I ran a 10 gauge power and ground wires. This is a huge improvement over the initial set up of the Kenwood running direct to the 4 Infinity speakers, which was terrible. Adding the Alpine Amp will not over power the speakers and vastly improves the quality of sound. Finally the sub rounds it out and brings it to a nice acceptable sound. It's not Harmon Kardon, but it sounds full

Pros: easy to wire, not bad on space, improved the overall sound quality of my system

Cons: not quite as powerful as I had hoped.

Overall a good solution for simple install, just a little spendy little sub. Not much else out there for a all in one amplified unit. Sounds good- Hopefully it holds up.

Repeat

madgadget from Missouri on 7/1/2015

Verified customer (What's this?)
Verified employee purchase (What's this?)

This is my 3rd bazooka but first new one. My 2 previous boats had 8" bazooka tubes. There's no denying that a pair of 10" can pound harder but for all of the associated baggage I'll take the trade of a little less bass for more room and convenience. When we park in party cove our pontoon system gets compliments and I imagine the new runabout will too. Even though my head unit has sub out and level control I ordered the remote gain and xover control because it's easier than navigating through menus to adjust output. These tubes just work, sound good, all in a small footprint. On a boat or any vehicle within reason it's difficult to get more thump for your $$. imo

Pros: tight bass in a small footprint

Cons: not free

Loved it

Straight forward installation - product performs flawlessly on my aft-cabin boat - has totally changed the sound on board...can't recommend it enough.

Pros: Looks good - sounds great

Cons: Only thing I wish they had was an elegant cover/conduit for the back of the unit to hide the two sets of cables until you can get them behind a wall. Ended up taping them tightly but that part could look better

Features

Marine Grade Construction: The MBTA8250D features an 8" waterproof poly woofer. The woofer is powered by a built-in 160-watt (250 watts peak) digital amplifier. The patented Bass Tube enclosure design eliminates bass standing waves for high accuracy, and superior efficiency. The enclosure is certified salt fog and UV resistant for 5 years and the included mounting hardware is stainless steel.

Low-pass Filter: The MBTA8250D has a low-pass filter that can be adjusted from 60 to 250 Hz.

2nd Woofer Output: The MBTA8250D has a high-level output for adding an optional MBT8014 (204MBT8014) passive bass tube to double the bass. The amplifier output increases to 275 watts (peak) when the 2nd woofer is connected.

Remote Level/Crossover Control: Using the optional RBCM-250D remote control (204RBCM250), you can control the bass output level and crossover frequency of the subwoofer from a remote location.

Controls

Level Control: There is a rotary control on the rear-panel that allows you to adjust the level of the subwoofer.

Crossover Control: The unit's rotary control is found on the rear-panel and allows you to adjust the low-pass filter from 60 to 250 Hz.

Power LED: If power, ground and remote are connected properly, the LED on back of the unit will illuminate in green.

Connections

Remote Control: Phone-type jack for use with an optional remote control; found on rear-panel

Power Harness: Two quick-slides for use with supplied power harness; found on rear-panel

Signal Harness: 14-pin Molex plug for use with supplied signal harness

Installation

Installation: Each mounting strap has an attached mounting base that can be secured to your vehicle using the supplied self-tapping screws. Once the mounting bases are installed, the tube is held in place by the mounting straps. For best results, the tube should be mounted facing into a corner, and there should be 2" to 4" between the woofer and the corner into which the woofer is pointing.

Required Accessories:

  • Power Wire: The 12-gauge power lead is only 11" long, so additional wire is required to extend it to the battery. Additional power wire must be crimped or soldered to the Bazooka's power lead.
  • Ground Wire: The 12-gauge ground lead is also only 23" long, and may need to be extended. Additional ground wire must be crimped or soldered to the Bazooka's ground lead.
  • Speaker Wire: required only when using the high-level inputs
  • RCA Patch Cord: required only when using the low-level inputs
  • Remote Turn-on Wire: required to connect the remote turn-on lead to the amplifier turn-on lead of your radio
